    glais, reduced to a medium of 28 inches of the barometer and 54.5° of the thermometer, at the commencement of the experiment was about 50 cubical inches. At the end of the experiment the remaining air, reduced to the fame medium preflure and temperature, was only between 42 and 43 cubical inches ; confequently it had loft about ¢ of its bulk. Afterwards, having col- lected all the red particles, formed during the experiment, from the running mercury in which they floated, I found thefe to amount to 45 grains. I was obliged to repeat this experiment feve- ral times, as it is difficult, in one experiment, both to preferve the whole air upon which we operate, and to collect the whole of the red par- ticles, or calx of mercury, which is formed du- ring the calcination. It will often happen in the fequel, that I fhall, in this manner, give in one detail the refults of two or three experi- ments of the fame nature. The air which remained after the calcination of the mercury in this experiment, and which was reduced to £ of its former bulk, was no longer fit either for refpiration or for combuf- tion ; animals being introduced into it. were fuf- focated in a few feconds, and when a taper was plunged into it, it was extinguifhed, as if it had been immerfed in water. . 2 In
